Extrusion International 3-2019

24 Extrusion International 3/2019 PROFILE EXTRUSION The milling unit is aimed at processing round holes along the extrusion axis of the 4-wall boxed profile, with the flexibility of managing different punching patterns, set by the operator panel. The dedicated milling tools are studied for the machining of various types of inserts in or- der to minimize the material removed and allow a clean cut without burrs. The oil-bath mandrel system, that en- sures a lasting and excellent refrigeration, has a multiple movement to hold the removed disk and the subsequent release at the end of the process. The scraps of the mill- ing process are sucked by the powerful system aspirator, while the milled disks fall into the appropriate collection channels and from there conveyed on the belt that un- loads them in the special container placed at the exit of the cabin, for the subsequent recycling . Thanks to its structure and special customized software, the system also offers the great advantage of being used both in and out of line. Baruffaldi always takes in consideration to have a safety work environment. The two 2 tunnels (in and out) and the soundproofed safety cabin comply with safety regu- lations as the processing noise is much lower than the re- quirements of the related regulation admitted on work- ing environments. The MILL/8 has a user friendly operator panel and an easy routine maintenance. Moreover, the remote assistance system allows Baruffaldi to give imme- diate assistance to the customer, acting side by side. In inline mode, the brushless motor – which manages the longitudinal movement of the carriage along the extru- sion axis – together with the encoder, guarantee the per- fect synchronization of the carriage with the extrusion speed of the profile. Currently equipped with 4 independent modular milling tool sets, the machine is able to process the profile at a process speed of 1 m/min. both in- and outline. Thanks to the doubling of the milling heads, the speed would also reach 2 m/min, with high performances in terms of quality and speed. The R&D team of the Baruffaldi-Primac technical office has given life to a plant of considerable dimensions, in which innovation, modularity, flexibility and technology are successfully combined with solidity, robustness and precision. The new Baruffaldi plant improves the quality of the product profiles and optimizes the production pro- cess with a reduction in costs.
